Question

To which series would the emitted light belong if an electron in a hydrogen atom underwent a transition from level n = 5 to level n = 1?

Answer 1

So we want to know in which series would the emitted light belong if the electron in a hydrogen atom would go from the energy level n=5 to n=1. The correct answer is Lyman series. Complete Lyman series is from energy level n=6 to n=1. All of the wavelengths in the Lyman series are in the ultraviolet part of the electromagnetic spectrum.
